Answer:
The probability that the result is positive is P=0.04475=4.475%.
Step-by-step explanation:
We have the events:
D: disease present
ND: disease not present
P: test positive
F: test false
Then, the information we have is:
P(D)=0.005
P(P | D)=0.99
P(P | ND)=0.04
The total amount of positive test are the sum of the positive when the disease is present and the false positives (positive tests when the disease is not present).
![P(P)=P(P | D)*P(D)+P(P | ND)*(1-P(D))\\\\P(P)=0.99*0.005+0.04*0.995\\\\P(P)=0.00495+0.0398=0.04475](https://tex.z-dn.net/?f=P%28P%29%3DP%28P%20%7C%20D%29%2AP%28D%29%2BP%28P%20%7C%20ND%29%2A%281-P%28D%29%29%5C%5C%5C%5CP%28P%29%3D0.99%2A0.005%2B0.04%2A0.995%5C%5C%5C%5CP%28P%29%3D0.00495%2B0.0398%3D0.04475)
The probability that the result is positive is P=0.04475.
Answer:
140yd2
Step-by-step explanation:
Let
One Number = x
Second Number =x-10
Third Number=x/2
Sum of three numbers is 50
x+x-10+x/2=50
2x-10+x/2=50
Multiply by 2 both sides
2*(2x-10+x/2)=50*2
4x-20+x=100
5x=100+20
5x=120
x=120/5
x=24
One number = x=24
Second number =x-10=24-10=14
Third number= x/2=24/2= 12
Answer:
So, 35 degrees is your answer.
Step-by-step explanation:
180 - 100 - 45 = 35 degrees

Answer: ![y=5x-6](https://tex.z-dn.net/?f=y%3D5x-6)
Step-by-step explanation:
use point-slope form
![(y-y_{1}) =m(x-x_{1})](https://tex.z-dn.net/?f=%28y-y_%7B1%7D%29%20%3Dm%28x-x_%7B1%7D%29)
plug in given values where m is slope and y1 and x1 are values
![y-(-1)=5(x-1)](https://tex.z-dn.net/?f=y-%28-1%29%3D5%28x-1%29)
![y+1=5(x-1)](https://tex.z-dn.net/?f=y%2B1%3D5%28x-1%29)
![y+1=5x-5](https://tex.z-dn.net/?f=y%2B1%3D5x-5)
![y=5x-6](https://tex.z-dn.net/?f=y%3D5x-6)
